Answer:

x = 8

Step-by-step explanation:

3x - 20 = 4

add 20 to both sides

3x - 20 + 20 = 4 + 20

3x = 24

divide both sides by 3

\frac{3x}{3} = \frac{24}{3}

x = 8

How did i work this out?
bogdanovich [222]

knowing the answer is between 3 & 4 plug those as x and see what you get for answers than adjust the number accordingly

3^3+2(3) = 33 so its higher than 3

4^3 + 2(4) = 72 so it is lower than 4

try the middle so try 3.5

3.5^3 + 2(3.5) = 49.875

question states use 1 decimal place so now try 3.6

3.6^3+2(3.6) = 53.856


3.5 is closest

mars1129 [50]
The answer is 93 

If we sorted out the number of each hours, the sequence will look like this

57 _    69  _  81  _ x  _ 105   

(in which x is the fourth hour of work)


We can see from the sequence that each hours, the mailman add additional 12 letters.
(69 - 57 = 12)
(81 - 69 = 12)   . . . . proof


So, the amount of letters on the fourth hour would be:
81 letters  + 12 letters = 93 Letters
